Brown and Rihanna have apparently had similar splits in the past, with an insider suggesting that it is likely that they could still get back together.

Neither star has yet commented directly on the split rumors, although Brown has since been linked to a Los Angeles-based waitress named Kiesha Kimball.

Brown and Kimball were photographed holding hands during an outing over the weekend at LA club Playhouse.

Kimball has now spoken out to the website to insist that she is in fact not dating Brown, particularly because she is not attracted to black men.

"I am always Chris's waitress. I know him and am friends with his friends," Kimball said. "Nothing has ever happened. I just work there. In the photos, he was handing me a bottle to drink out of. Of course people are going to twist it another way. I don't go for black guys."

The waitress went on to insist that her personal preference is not in any way racially motivated and added: "Whatever is going on between Rihanna and Chris Brown is between them. I'm not trying to be a home wrecker."

Brown has spent the last several weeks on the promotional circuit and has spoken openly about his and Rihanna's relationship.
